Join us for the A S Harrison & Co Fuels & Lubricant Additives Conference 2024, taking place at the elegant Four Seasons Hotel in The Rocks, Sydney. Following the conference, we invite you to join us for an evening event at Bar Ombre, an exciting roof top bar only 5 minutes walk from the conference. […]
Thank you so much to all who attended the A S Harrison & Co Fuels & Lubricant Additives Conference 2023 on 14 November. We really enjoyed it and hope you did too. The varied discussions touched on several aspects of the business as well as how A S Harrison & Co has weathered the storms […]
Dynamico was developed specifically to offer optimal performance for all gasoline engines whilst preventing the formation of deposits on inlet valves and fuel injectors, and cleaning the existing inlet valve and injector deposits. This way, the fuel delivery systems delivers simultaneous efficiency and particle emissions reduction. After adding Dynamico to fuel, it will immediately works […]
Optimum fuel performance in today’s high-performance engines With a content less than 15ppm sulfur, ultra-low sulfur diesels (ULSD) provide cleaner options to traditional fuel mixtures. The challenge during the desulfurisation process is that the action of removing sulfur from the fuel stream can cause problematic effects on the fuel properties themselves. This includes having negative […]
With the continued delay of the ILSAC GF-6 specification, the API (American Petroleum Institute) is developing an official API SN Plus specification. The API SN Plus specification is not a replacement for ILSAC GF-6 but will act as a supplemental category alongside the current API SN and ILSAC GF-5 categories. The need for the API […]
Oronite has again demonstrated a strong commitment to top-tier PCMO requirements. Vauxhall OV0401547 is the latest specification to join OLOA® 54720’s growing list of approved new tier specifications. OLOA® 54720 additive has received the official consent from ‘Opel/Vauxhall’ for the OV0401547 specification. Oil manufacturers can now use OLOA® 54720 to manufacture licensed finished oil meeting […]
Product and customer insights
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
